电解液分压器的优化设计

Optimum Design of a Aqueous-electrolyte Divider

为了避免脉冲分压器的杂散参数的影响,笔者采用非线性规划的复合形法对按传输线原理设计的电解液电阻分压器的结构参数进行了优化设计,通过分析优化结果得出:在满足测量精度和耐压的情况下,分压器的尺寸越小越好;该型电阻分压器由于其自身结构的特点,要求硫酸铜液电阻的阻值尽量小;对该型电阻分压器进行优化设计时应综合考虑测量的要求。

In order to avoid spurious parameters of pulse divider, an optimum design was performed for the structure parameters of a novel aqueous-electrolyte resistance divider by using the complex method of the nonlinear programming problems. After analyzing the results of the optimum design, the following conclusions can be drawn： firstly, the smaller the dimensions of the divider are, the better its performance can be obtained when the measuring accuracy and withstanding voltage are satisfied; secondly, the resistance of copper sulphate should be as small as possible to match with the structure features of the resistance divider; lastly, the requirements of measurement should be considered in the optimum design.
